Let’s first look at the grades of tea green tea: Qingmao tea was unified into five and ten grades in 1979.

If you design a sample in pairs, it will be second-class and first-class. That is, two, four, six, eight, and ten are divided into five levels. Generally speaking, first-grade tender tea leaves are usually blended with second-grade tea leaves to make loose tea, Tuocha tea, square bricks, etc. Second-grade tea greens are blended with third-grade tea to make cake tea, while fourth- and fifth-grade tea greens are the main raw materials for brick tea.

Cha Qing refers to the leaves freshly picked from tea gardens, which are used as raw materials for processing into dry tea (finished tea). Generally, Tieguanyin tea has three leaves and one stem (or one bud and two leaves).
